I've never had this issue before with FabFilter plug ins, but I'm trying to open a logic session I was just working on, and all of a sudden, it's crashing before it'll load.. and the warning message says it has something to do with the ProQ3:
PlugIn Path: /Library/Audio/Plug-Ins/Components/FabFilter Pro-Q 3.component/Contents/MacOS/FabFilter Pro-Q 3
PlugIn Identifier: com.fabfilter.Pro-Q.AU.3
PlugIn Version: 3.11 (3.11)
Please help if you can!
